WILLIAM HILL, OF MOUNT VERNON, ILLINOIS.

SAW-FILING MACHINE.

SPECIFICATION forming part ofLetters Patent No. 308,670, dated December2, 1884.

Application filed March 13, 1884. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM HILL, a citizen of the United States,residing at Mount Vernon, inthe county of Jefferson and State ofIllinois, have inventeda new and useful Saw- Filing Machine, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to a device for filing hand and other saws; and ithas for its object to provide a device of this character which shall besimple in its construction and effective in its operation.

A further object of the invention is to provide an improved track orguide for the file and a clamping device for holding the same, wherebythe le may be adjusted at any angle.

A further object of the invention is to provide improved means wherebythe frame carrying the le may be adjusted to bevel the teeth.

Vith these ends in view the invention consists in the improvedconstruction and combinations of parts hereinafter fully described, andpointed out in the claims.

In the drawings, Figure I is a perspective of my invention. Fig. 2 is aplan view of the same. Fig. 3 is a longitudinal vertical section throughthe file-guide. Fig. -l is a perspective view of the guide carrying thefile.

In the accompanying drawings, in which like letters refer tocorresponding parts in the several figures, A represents a base or platewhich is constructed of metal and provided on its under side with ribsc, which are adapted to engage with corresponding grooves in thesawclamp when the device is placed in position for operation. Upon therear side of this base A is provided a segmental plate, B, which isprovided with a series of teeth, b.'

At about the center of this plate or base A is pivoted a frame orcasting, C, which is provided at its lower rear end with a dependingbracket, D, having openings d, in which is mounted a bar or rod, E,having a squared head, e, to engage the teeth b of the segmentalrack-plate B. This bar or rod is held in engagement with said teeth bymeans of a coilspring, c', mounted upon said rod between the loops ofthe depending bracket and bearing against the squared head of the saidrod E. Upon the forward end of this frame or casting C is provided anoutwardly-extending arm, F, provided at its extremity with aperforation, f, through which passes a screw, f upon the end of which ispivotally secured the track or guide in which the file-carrier works.This guide G is provided on its in- 'ner side adjacent to the casting Cwith a setscrew, g, which works in a slot, g', formed in said casting,whereby the file-guide G may be vertically adjusted the length of saidslot and secured at any point thereon by tightening the said set-screw.

H represents the devices for holding the file, the same consisting ofthe side portionsh, having flanges 7L at their upper ends, which flangesrest upon the upper edges of the guide G and the lower ends or edges ofthe sides lz, which rest upon the bottom of the guideframe G.

At the forward end of the side portions h is provided a tubular portion,h2, having a screwthreaded opening in its upper face, in which is seateda set-screw, h3.

I represents a rod or handle for sliding or operating the file-carrier,and which passes through the tubular portion 762, and is held `rigidlytherein by means of the set-screw 71.3.

Upon the forward end of the sliding rod I is provided a loop, fi, whichencircles the same. To the upper ends of this loop, and between thesame, are secured two arms, J, which are provided at their forward endswith clamping portions j to receive the le, which is held rigidlytherein by means of a setscrew, j', passing through screw-threadedopenings j2 in the ends of the same. The forward end of the sliding rodI is made hollow or recessed, and in said recess vis a plug of cork,wood, or other material, in which the end of the file is inserted.

Upon the upper face of the tubular portion h are graduated marks 7c, andupon the sliding rod is provided an indicator or bent arm, whereby uponloosening the set-screw in the upper side of the tubular portion thesliding rod may be adjusted at any point desired.

The operation of the device as above described is as follows: Thesaw-clamp for holding the saw while it is being sharpened is providedwith grooves x and z, for the reception of the outer edge of the plateor base A and the ribs upon the under side thereof. The

ICO

saw is placed between the clamp and the sawguide vertically adjusted bymeans of the setscrew which works in the slot formed on the side of thecasting C", and the said casting C,whieh carries the file-guide, is adjusted to the desired angle by means of the segmental rack and thespring-pressed rod which engages the same. The sliding rod carrying theiile may then be turned or adjusted by means of the set-screw of thetubular portion so as to bring the edge of the file at the desiredangle, in order that the extremity between the teeth may be sharp cnedor made deeper.

It will be seen from the above description that in sharpening sawsthcile may be adjusted to sharpen the sides of the edges of the same, tomake the recess or cavity between the teeth deeper, and that the armsholding the iile may be adjusted for the reception of files of varioussizes. It will also be seen that the device may be readily attached toor detached from the clamp holding the saw in position while beingsharpened.

Having fully described my invention, what Iclaim as new, and desire tosecure by Letters Y Patent, is*

l. In a saw-iiling machine, the combination, with a base-plate providedon its under side with ribs, and having asegmental rack-plate, of aframe, C, pivoted to said base, a lile-car rier guide-frame pivoted tosaid frame C, said gnideframe being adapted to be vertically adjusted onthe frame C, and a iilccarrier, substantially as set forth. 2. Thecombination, with a suitable baseplate provided on its under side withribs, and having a segmental rack-plate arranged upon its rear side, ofa frame pivoted thereto, a spring-pressed rod to engage said rack-plate,afle-carrier frame pivoted to the frame C, and a file-carrier, as setforth.

3. The combination, with a suitable baseadapted to receive and retain afile, as set forth.

5. The herein-described file-carrier, consisting of the flanged tubularportion, a rod mounted in said tubular portion, and adjustably securedby means of a set-screw, and two forwardlyextending arms provided withclamping portions and a set-screw, to accommodate iiles of varioussizes, substantially as set forth.

6. The herein-described file-carrier, consisting of the tubular portion,a rod adjusta-n bly secured in said tubular portion by means of aset-screw, a loop encircling said rod, to the upper ends and betweenwhich are secured clamping-arms adj ustable attheir ends by means ofaset-screw, the end of said rod being recessed and provided with a plugof cork, wood, or other suitable material for the reception of the endof the le, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aixed mysignature in presence of two witnesses. r l

IILLIAM HILL.
